PRINTING PRESS Filed Nov. 24, 1957 Y A TTORNEY INVEI VTOR. ward Patented Sept. 27, 1938 Appiaaitnjme'm er 24, 1937, SeralNo. 176,275

The present invention has relation to printing presses and the main object of this invention is to provide a miniature press operating as a useful and instructive toy.

The improved miniature press is so designed that all the essential parts of an operating press are included whereby a comparatively inexperienced juvenile person may therewitheffect printing on cards or sheets of a size within the capacity of the press.

With this miniature press most of the parts thereof are made of sheet metal stamped out and so arranged and constructed that these parts may be produced and assembled at a comparatively low cost so that the press can be sold at a low price as an operating and useful toy. The construction and design of the press is such that the packing and handling of the press is facilitated. Furthermore, the design is attractive in appearance which may tend tomaterially aid in the sale of the press.

The invention consists mainly of the particularconstruction and arrangement of the component parts or elements of the improved structure as will be hereinafter more'fully described with reference to the accompanying drawing wherein:

Figure 1 is a plan view of the improved press,

and v Figure 2 is a side elevation thereof. Referring to said drawing, as previously stated the improved press has all the essential. parts which render the construction useful for practical printing in a moderate way, and accordingly the improved press shown in the drawing comprises a supporting frame'composed of a pair of sheet metal side members and 2 having turned in stiffened edges 3. These members for strength and appearance are united by rivets 4 to the base 5 comprises cross-bars 6 secured by bolts to said base 5.

The operative members of the improved press include the operating table I which is secured at havmg the amusement produce usefulwprmtmg each side by block 8 and pins 9 to the upper ends of the supporting members I. Inking pad IO'is mounted and secured on-the upper ends of the supporting members 2. The type block I I carrying type is also mounted on the upper ends of the press 2 and is arranged to slide vertically in a slideway defined by turned in portions l2 and this block is held in position by a wire |3 secured to the block and bearing on the holder 14 for theinking pad :|0. .The blockll is groovedhorizontally so as to receive the type l5.

With the simplest and most economical form of the improved press preferably rubber type would be employed and the type block is preferably made of wood. The block closelyffits within the slideway or track holding the same whereby an even'impression can be obtained in the printing operation. It will be understood, however, in a moreexpensiveform of the improved press metal type and a metal block would be employed so as to get fine adjustment for better printing.

The improved press has the platen I6, which is connected by a system-of links l! with theinking roller l8 and operating lever IS in such a manner that on the upward movement ofisaid lever the sheet on, the platen will be brought in contact with the type and in the same movement the inking roller I8 is caused totravelover the inking pad Ill. When the lever I9 is broughtto its down position the inking roller picks up ink on the pad and inks the type for the next impression. To insure perfect contact of the inking roller with the type .II pressure is exerted by the spring 20.

and pivoted thereto at22. The links 2| are'connected together by a tie-bar 23 so astooperate in unison. The links 2| at the free ends are pivotally connected to hangers 24' which-carrythe inking roller l8. Links 25 pivoted on links 2| are pivotally connected to a strip 26 secured on the'under side of the platen Ma. y A single centrally located connecting'rod or link 21 is pivotally connected to a crank 28 and whichcrank is carried by the shaft 29 to which the operating lever I9 is secured. The mechanism or working.

parts of the printing press are so constructed and the platen and inking roller so that an even pressure of the platen and inkingof the type is obt ained and thereby the operator may, besides work. 1

Various modificationsmay be made in carrying out the details of the invention hereinbefore described, and it is to'be understood that any modification coming" fairly within the terms of the appended claims shall be covered thereby.

I claim:

1. A printing press of the class described'comprising a supporting frame, an oscillating platen, an inking roll, a hand lever for operating said p 40 arranged that an equalized movement is given-to platen and roll, a link system coupling said lever with said platen and said inking roll, said link system comprising a crank device operated by said lever, a pivoted link connection between said crank and said platen, a pair of links pivoted one on each side of said frame carrying said inking roll, a pivoted link connection between said platen and each of said inking roll carrying links and a tie bar uniting the latter links together.

2. A printing press of the class described com prising a supportingframe, an oscillating platen, an inking roll, a hand lever for operating said platen and roll, a link system coupling said lever with said'platen and said inking roll, said link system comprising a crank device operated by said lever, a pivoted link connection between said crank and said platen, a pair of links pivoted one on each side of said frame carrying-said inking roll, a pivoted link connection between said platen and each of said inking roll carrying links,,a tie bar. uniting the latter links together.

pivoted link connection between said platen and each of said inking roll carrying links, a tie bar uniting the latter links together, said frame comprising a pair of side members mounted on a supporting base and said members being each composed of a pair of crossed sheet metal plates united together.
